What it means
When both seller and buyer are Greek, each existing cac:AccountingCustomerParty/cac:Party/cbc:EndpointID must have schemeID equal to 9933 and a value that passes the Greek TIN check. The XPath does not separately check whether the document is being sent through Peppol, and it does not detect a missing cbc:EndpointID.
Why it matters
Scheme 9933 identifies the buyer's electronic address as a Greek TIN. The address value must match that identifier type. Passing this check does not confirm delivery or acceptance.
How to fix it
Ask the buyer to confirm the TIN used for their electronic address. If they give you a Greek VAT number starting with EL, use its nine-digit TIN part without that prefix. Put it in cac:AccountingCustomerParty/cac:Party/cbc:EndpointID with schemeID set to 9933, then check the corrected file again.
